This equation can be simplified to 200n + 1000. Now we can just plug in the amount of customers. 200 * 8 + 1000 = 2600. 200 * 12 + 1000 = 3400. 200 * 20 + 1000 = 5000, and 200 * 30 + 1000 = 7000.

A data set has a mean of 7, a median of 5, and a mode of 8. Which of the numbers (7, 5, or 8) must be in the data set?

If possible, please explain in words, thank you. :)

Answers

5 must be in the data set: median means it’s the middle number in the set. so if the data was [2,3,5,6,7], 5 is the median.

8 has to be in the data set because 8 had to be there to be a mode were you can have 5 as the median if the set was like this 234678 because 4&6 both are in the middle so you have to do the middle of that which is 5 so that’s the median without having the number 5.

I will solve these equations algebraically.

Here you are:

1. 30= 5w

Divide each side by 5.

30÷5= 5w÷5

6 = w

∴ w= 6

To check,

30=5w

Substitute w for 6

30= 5 x (6)

30= 30

LS= RS

(You were correct, great job!)

12 = x÷4

Multiply each side by 4.

12 x 4 = x/4 x 4 ↔ 4 and 4 cancel out.

48= x

∴ x=48

Checking:

12= 48÷4

12= 12

LS=RS

y÷5=15

Multiply each side by 5.

y÷5 x 5= 15 x5

y =75

∴y=75

Checking:

Substitute y for 75.

y÷5=15

75÷5=15

15=15

LS=RS

18x=72

Divide each side by 18.

18x ÷ 18= 72÷18

x = 4

∴x= 4

Checking

18x=72

18(4)=72

72=72

LS=RS

Step-by-step explanation:

given that there is one possible outlier. if the outlier was removed from the data set, how would it effect the measures of central tendency? {8, 73, 74, 75, 79, 85, 85, 92, 94}
(not links)
O Mean increases median decreases
O Mean decreases median increases
O Both mean and median increase
O Both mean and median decrease

Answers

Answer:

Some measures I believe you are talking about are mean, median, mode, and range.

Mean is the average of all values. This is found by adding up all numbers and dividing by the amount of numbers. Outliers greatly affect and "throw off" the mean, making it inaccurate at calculating the average without an outlier.

Example:

1, 2, 4, 6, 10

(1 + 2 + 4 + 6 + 10)/5 = mean = 4.6

1, 2, 4, 6

(1 + 2 + 4 + 6)/4 = mean = 3.25

Because of this, mean does change when adding and removing outliers, and is therefor not the answer.

Median is the middle of the data. This is found by ordering the values in the data set from least to greatest (or greatest to least, either one works) and finding the number in the center of all the values. If there were an outlier, the median wouldn't be skewed as the mean is by outliers, but it would change.

Example:

1, 2, 4, 6, 10 Median = 4

1, 2, 4, 6 Median = 3

So median is not the answer, because it is affected by adding and removing outliers.

Mode is the value in a data set that appears the most. Outliers are numbers that are significantly lower or higher than most or all of the other numbers in a data set. Because of this, there can't be more outliers than other numbers, so it is impossible for the mode to be an outlier.

Example:

1, 1, 1, 2, 3, 4, 4, 86 Mode = 1

1, 1, 1, 2, 3, 4, 4 Mode = 1

This means the mode is not affected by adding and removing outliers.

Mode is a possible answer, but let's take a look at range before coming to a conclusion.

Range is the spread of values in a data set. In other words, the difference between the highest and lowest value. A high range can signal a possible outlier is present.

Example:

1, 2, 4, 6, 10

10 - 1 = highest value - lowest value = range = 9

1, 2, 4, 6

6 - 1 = highest value - lowest value = range = 5

The range is certainly affected by outliers, so it is not the answer.

Out of mean, median, mode, and range, the answer to this question is mode.

If an outlier is removed, mode will not change.

Hope this helps!

Step-by-step explanation:

A variable term is one that contains one or more variables, possibly with a coefficient. We can use 47xy as our variable term.

A constant is some number, or a representative of a particular number. π and e and Ф are representative of irrational constants. Of course, any number is also a constant. We can use 6√3 as our constant.

A quotient is formed when a first value is divided by a second value.

Here is the quotient of our variable term and our constant:
